A new stereoselective synthesis of chiral ??functionalized allylic amines

Chiral t-Boc protected propargylic amines have been obtained starting from aminoaldehydes derived from natural aminoacids. Stannylcupration of these substrates affords an easy regio- and stereocontrolled route to the corresponding ?-stannylated (E)-allylamines which are useful intermediates for the synthesis of the corresponding ?-funtionalized allylic systems
